Address: 0x64 - 0x65
Type: R/W
Software Reset: 0x46 | 0x5B
Hardware Reset: 0xNA | 0x5B
The registers are considered logically concate-
nated and contain the fractional values for the
PLL, used to select the internal configuration.
After Reset, the values are NA, and the opera-
tional setting are done when the MPEG synchro-
nisation is achieved.
The following formula describes the relationships
among all the STA013 fractional PLL parameters:

where:

These registers are a reference for 48 / 24 / 12 /
32 / 16 / 8KHz audio.

Address: 0x67, 0x68, 0x69
Type: RO
Software Reset: 0x00
Hardware Reset: 0x00
The three registers are considered logically con-
catenated and compose the Global Frame
Counter as described in the table.
It is updated at every decoded MPEG Frame.
The registers are reset on both hardware and
software reset.

AVERAGE_BITRATE is a read-only register and
it contains the average bitrate of the incoming bit-
stream. The value is rounded with an accuracy of
1 Kbit/sec.
